The V/f pattern settings are incorrect.
•
Examine the ratios between the V/f pattern frequency and
voltage. Decrease the voltage if it is too high compared to the
frequency.
•
Adjust
E1-xx [V/f Pattern Parameters]
settings. For motor 2,
adjust
E3-xx [V/f Pattern for Motor 2]
settings. For motor 3,
adjust
E7-xx [V/f Pattern for Motor]
settings.
Torque compensation gain is too large.
Decrease the value set in
C4-01 [Torque Compensation Gain]
so
that the motor does not stall.
A malfunction occurred due to noise.
Check the control circuit lines, main circuit lines, and ground
wiring, and minimize the effects of electrical interference.
The gain during overexcitation operation is set too
large.
•
Identify the timing under which the fault occurs.
•
If the fault occurs simultaneously with overexcitation
operation, reduce the value set in
n3-13 [Overexcitation
Deceleration Gain]
, considering the motor flux saturation.
The drive received a Run command while the motor
was coasting.
Reevaluate the sequence to ensure that the stop command is input
after the motor has come to a complete stop.
The control method is not set correctly for the
motor being used.
Set
A1-02 [Control Method Selection]
correctly.
The motor main circuit cable is too long.
Replace the drive with a larger capacity model.
Note:
•
Occurs if the drive sensors detect a drive output current exceeding the specified overcurrent detection level.
•
Do a Fault Reset to clear the fault.
